Hi Jonah, I commented on your Gist. tl;dr - your requestAvatarId method isn’t returning the Deferred you create for the database query, to which your callback is attached. Hope this helps, Daniel -- L. Daniel Burr ldanielburr@me.com (312) 656-8387 On July 11, 2018 at 10:38:47 PM, Jonah Crawford (jonah.crawford@gmail.com) wrote: Glyph. I'll put this into SSCCE and resend in the am. Thanks for looking. On Jul 11, 2018, at 8:31 PM, Glyph <glyph@twistedmatrix.com> wrote: Hi Jonah! Can these examples be made into SSCCEs <http://www.sscce.org>? They're missing all their imports and, for example, replacing the database calls with some succeeded/failed Deferreds? I'd love to help but I'd rather not debug a bunch of zope component lookups (I'm assuming that's what getUtility is) and DB queries that are irrelevant to the problem at hand :). -g On Jul 11, 2018, at 3:48 PM, Jonah Crawford <jonah.crawford@gmail.com> wrote: I've posted code here: credential checker --> https://gist.github.com/minskmaz/ab218d7b137b24ede8ffc7e3ea6e2392#file-crede... realm.py --> https://gist.github.com/minskmaz/ab218d7b137b24ede8ffc7e3ea6e2392#file-realm... session wrapper --> https://gist.github.com/minskmaz/ab218d7b137b24ede8ffc7e3ea6e2392#file-webau... As I point out on line 14 of realm.py the checker is matching a password against the db but its requestAvatarId (line 10 of credentialChecker.py ) is returning None to requestAvatar Any guidance warmly welcomed.
